P.S.I.: A Pessimistic Sense of Inadequacy is a webcomic by Fesworks, taking place in a world co-inhabited by humans and anthropomorphic animals. The main characters of the comic include Fes (a human representation of Fesworks), Ernst (an albino rat), and Nemi (a "wererabbit" in the simplest terms). Genre savviness and "fourth wall" breaks are a recurring theme.
